What Is The DISC Profile? Who Created The DISC Model?
Written by John C Goodman, MSOD, MSW, LCSW
In addition to Martson's work on DISC, understanding personality-behavior-environment relationships, emotional intelligence (before it was called emotional intelligence), and behavioral styles he also developed the original lie detector. Another interesting aside is that Marston also was the creator of “Wonder Woman,” where he introduced the strong female super hero into comic strips.
For about 40 years DISC has continued to evolve. From Marston's original development of the D.I.S.C. model; to the research conducted by the University of Minnesota's Dr. John Geier and other researcher and assessment developer.
Irony Marston developed the D.I.S.C. model he never copyrighted his disc profile test. Yet, today, 75 years after the publication of his book, over 5 million people have taken various forms of the DISC profile throughout the world. Marston’s original work continue to be enhanced by ongoing behavioral research and profiles can be found in than 50 languages by various publishers of the disc assessment. With this evolution of various versions of the DISC of varying quantity and validity. There are numerous people and companies trying to capitalize on the DISC and Marston's original work. DISC Classic 2.0 Profile and the PPSS or Personal Profile Software System Profile offer a 28 question model of the DISC in order to provide what we believe to be a highly valid, reliable instrument presented in a very user-friendly way that is applicable to not only business applies, but family, social and personal relationships.
The DISC model is a nonjudgmental tool for understanding behavioral types and personality styles. It helps people explore behavior across four primary dimensions:
Dominance: To the point, decisive and bottom line oriented. These people tend to be independent and results driven. They are strong-willed people who enjoy challenges, taking action, and immediate results.
Influence: Optimistic and outgoing. They tend to be highly social and out going. They prefer participating on teams, sharing thoughts, and entertaining and energizing others.
Steadiness: Empathetic & Cooperative. These people tend to be team players and are supportive and helpful to others. They prefer being behind the scene, working in consistent and predictable ways. They are often good listeners and avoid change and conflict.
Conscientiousness: Concerned, Cautious & Correct. These people are often focused on details and quality. They plan ahead, constantly check for accuracy, and what to know "how" and "why".
